Wars in Skyrim - Random enquanters, able to choose the difficulty, some minor additional changes. Pretty fun to increase the chance of random fights. Plus the Heroes and Villains addon that is very fun but may be difficult for low level players.
Warzones - small to huge battles between different factions, battlegrounds, etc. Many NPCs added.
The mods don't conflict with each other.
Nice, wwas wondering how well they played together. Did try 1.41 WIS, but my new mage character is a bit squishy still (although lvl 49 sneaky archer is complete opposite).
Will wait until my mage has levelled up a bit more before trying again. Could have broken it too, as forgot to delete WIS 1.41 before installing 4.0.
